mfd: ntxec: Add version number for EC in Tolino Vision

2023-02-22T11:42:29+00:00

The EC firmware has a different version number than anything defined until now. Signed-off-by: Andreas Kemnade Signed-off-by: Lee Jones Link: https://lore.kernel.org/r/20230127165828.3256170-1-andreas@kemnade.info

mfd: ntxec: Change return type of ntxec_reg8 from __be16 to u16

2021-12-29T13:41:20+00:00

Register values in NTXEC are big-endian on the I2C bus, but the regmap subsystem handles the conversion between CPU-endian and big-endian data internally. ntxec_reg8 should thus return u16, not __be16.

mfd: ntxec: Support for EC in Tolino Shine 2 HD

2021-04-14T15:06:29+00:00

Add the version of the EC in the Tolino Shine 2 HD to the supported versions. It seems not to have an RTC and does not ack data written to it. The vendor kernel happily ignores write errors, using I2C via userspace i2c-set also shows the error. So add a quirk to ignore that error. PWM can be successfully configured despite of that error.

mfd: Add base driver for Netronix embedded controller

2021-03-10T11:06:27+00:00

The Netronix embedded controller is a microcontroller found in some e-book readers designed by the original design manufacturer Netronix, Inc. It contains RTC, battery monitoring, system power management, and PWM functionality. This driver implements register access and version detection. Third-party hardware documentation is available at: https://github.com/neuschaefer/linux/wiki/Netronix-MSP430-embedded-controller The EC supports interrupts, but the driver doesn't make use of them so far.
